在Daemon线程运行中我在Eclipse Console 随意输入字符怎么没有用啊

public class DaemonThreadDemo {
/**
* @param args
*/
public static void main(String[] args) {
System.out.println("进入Main线程 " + Thread.currentThread().getName());
ThreadDaemon daemonThread = new ThreadDaemon();
Thread t1 = new Thread(daemonThread, "DaemonThread1");
t1.setDaemon(true);
t1.start();
Scanner sc = new Scanner(System.in);
sc.next();
System.out.println("退出Main线程 " + Thread.currentThread().getName());
}
}
class ThreadDaemon implements Runnable {
@Override
public void run() {
System.out.println("进入守护线程 " + Thread.currentThread().getName());
try {
writeToFile();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("退出守护线程 " + Thread.currentThread().getName());
}
private void writeToFile() throws Exception {
File fileName = new File("d:" + File.separator +"JavaDameonThread.txt");
OutputStream os = new FileOutputStream(fileName, true);
int count = 0;
while(count < 100) {
os.write(("\r\nHello Java" + count).getBytes());
System.out.println("守护线程 " + Thread.currentThread().getName()
+ "向文件中写了 Hello Java " + count++);
Thread.sleep(1000);
}
}
}
